Customer Question

Re. Smeg gas hob.
The large top left ring lights but won't stay alight for more than a few seconds. If I relight it several times it remains on for a little longer each time but always goes off again. What's the answer?

Hello, my name is George..
The problem will be caused by a failing or badly connected thermocouple.. If the valve cannot detect the 30mv produced by the thermocouple as it heats, the valve will shut down.
Try tightening the thermocouple joints at the valve and ensure that the body of the thermocouple is well earthed.
